Description

The fully differential $\bar B \to D^* ( D \pi, D \gamma) \ell^-{\bar \nu}_\ell$ angular distributions are considered to scrutinize the effects of the $B \to D^{(*)}$ form factor parametrizations.
The use of the angular coefficients to pin down deviations from SM is discussed, in particular concerning lepton flavour universality violation phenomena.
A possible connection between the tension in the inclusive/exclusive determinations of $|V_{cb}|$ and the $R(D^{(*)})$ anomalies is discussed.
